ARBITRON INC. REPORTS 2006 THIRD QUARTER FINANCIAL RESULTS
Revenue up six percent to $90.7 million;
Net income per share (diluted) is $0.68;
Costs and expenses increase due to planned spending on Portable People Meter and ‘Project Apollo’
initiatives and reporting of share-based compensation expense

NEW YORK, October 19, 2006 – Arbitron Inc. (NYSE: ARB) today announced results for the third quarter ended September 30, 2006.

For the third quarter 2006, the Company reported revenue of $90.7 million, an increase of 6.0 percent over revenue of $85.6 million during the third quarter of 2005.

Planned spending on the Portable People Meter and Project Apollo initiatives along with the required expensing of share-based compensation contributed to increased costs and expenses for the third quarter of 7.8 percent, from $52.7 million in 2005 to $56.8 million in 2006.

Arbitron’s equity in the net income (loss) of its affiliate, Scarborough Research, declined from $193 thousand in the third quarter 2005 to a loss of $1.8 million in the third quarter of 2006. This decline is due primarily to changes in the delivery schedule for Scarborough market reports.

Earnings before interest and income tax expense (EBIT) for the quarter were $32.1 million, a decrease of 3.0 percent over EBIT of $33.1 million during the comparable period last year.

Net income for the third quarter decreased by 3.4 percent from $20.9 million in 2005 to $20.2 million in 2006.

Net income per share for the third quarter 2006 was $0.68 (diluted) compared with $0.66 (diluted) for the third quarter 2005.

The increase in net income per share for the third quarter relative to the decrease in net income for the quarter is attributable to a reduction in shares outstanding due to the company’s repurchase of its shares in the first half of 2006.

For the nine months ended September 30, 2006, revenue was $250.0 million, an increase of 6.5 percent over the same period last year. EBIT was $73.1 million, compared to $84.4 million in 2005. Net income for the nine months was $45.7 million or $1.51 per share (diluted), compared with $56.1 million or $1.77 per share (diluted) during the comparable period last year.

Commenting on the company’s accomplishments in the third quarter, Stephen Morris, president and chief executive officer of Arbitron, noted: “We continued to push forward on Project Apollo as a new marketing research service for advertisers and on the Portable People Meter^SM System as the new radio ratings service in the top 50 markets.

“On the Apollo front, the World Federation of Advertisers – a network of 55 National Advertiser Associations and of over 40 of the world’s top 100 advertisers – officially endorsed the development of Project Apollo in the United States. And we continue to gather positive feedback and direction from the advertisers who are participating in the pilot panel for Project Apollo.

“Focusing on PPM^SM ratings, we began recruiting consumers for the Philadelphia Portable People Meter-based radio ratings service, continue to work toward Media Rating Council accreditation for the PPM in Houston and have signed additional major market broadcasters to PPM ratings agreements.

“Our efforts have not been confined to Portable People Meter initiatives. We unveiled a new service that helps advertisers, agencies and radio stations easily define whether a particular radio station meets the beer industry’s audience guidelines.

“Our Scarborough Research was fully accredited by the Media Rating Council, giving that service a significant competitive advantage in its marketplace.

“And we were the first national research firm to resume regular surveys in the Katrina-impacted markets of New Orleans and Biloxi.”

Arbitron is also providing guidance on its earnings outlook for the fourth quarter 2006 and for the full year 2006.

For the fourth quarter 2006, Arbitron expects revenue to increase approximately 5 percent compared to the fourth quarter of last year. Arbitron’s year-end 2006 revenue guidance is unchanged. As previously stated, 2006 revenue is expected to increase between 6 percent and 8 percent compared to 2005.

Earnings Per Share (diluted) for the fourth quarter 2006 is expected to be between $0.12 and $0.17 versus $0.36 in the fourth quarter 2005.

Arbitron’s fourth quarter 2006 Earnings Per Share guidance takes into account several factors.

In October 2006, Arbitron repaid its $50 million note, which had an above market interest rate and a number of terms that potentially limited the company’s financial flexibility. The pre-payment required the company to pay a “make-whole” interest payment to the note holders and also necessitated a write-off of the remaining balance of unamortized deferred financing costs. These two expenses will amount to approximately $2.9 million (pre-tax) or $0.06 per share (diluted) in the fourth quarter.

The impact of share-based compensation expense in the fourth quarter of 2006 is estimated to be approximately $1.3 million, or $0.03 per share (diluted).

The balance of the year-over-year reduction for the quarter is attributable to planned incremental spending on the PPM rollout in Philadelphia, New York and Los Angeles, as well as on some information technology spending that was previously planned to be spent in the third quarter 2006.

As a result of the previously noted $0.06 per share (diluted) expense related to the pre-payment of the $50 million note, Earnings Per Share (diluted) for the year ending December 31, 2006 is now expected to be between $1.63 and $1.68 versus the previously issued year-end guidance of $1.69 to $1.74 per diluted share, which did not contemplate the debt pre-payment.

(3) Earnings before interest and income taxes (EBIT) and earnings before interest, income taxes, depreciation and amortization (EBITDA) are widely used non-GAAP measures of operating performance. They are presented as supplemental information that management of Arbitron believes is useful to investors to evaluate the Company’s results because they exclude certain items that are not directly related to the Company’s core operating performance. EBIT is calculated by adding back net interest expense and income tax expense to net income. EBITDA is calculated by adding back net interest expense, income tax expense, depreciation and amortization to net income. EBIT and EBITDA should not be considered as substitutes either for net income, as indicators of Arbitron’s operating performance, or for cash flow, as measures of Arbitron’s liquidity. In addition, because EBIT and EBITDA may not be calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies.
